Microsoft Sharepoint error 0x80045b00

There are many errors that can occur when you try to use Microsoft SharePoint. One of the most common errors is Microsoft SharePoint 0x80045b00 error.

The problem can be caused by a server error, a network error or an issue with your computer or your internet connection. You might also encounter this error if other applications are interfering with the proper functioning of Microsoft SharePoint on your computer or if you have malware installed on your computer. To fix this error, you need to try a few solutions.

First of all, error 0x80045b00 is typically related to authentication problems. This error usually occurs when the security settings on your computer or on your network are incorrect. So, the credentials you use to access the computer or network must be correct. If you are using a guest account, you can log out and log in with a different account.

If you are having problems with the NTLM protocol, you can try to fix it by installing REST programs, such as Postman. You can then send requests to NTLM authentication. Make sure you are using the correct credentials and that you are using the correct server. The process would be:

1. Request to NTLM Sharepoint
2. If authenticated, an authentication token will be returned in the HTTP headers
3. Request with this token will be sent to the Sharepoint Server
4. Sharepoint will check the authentication token in the HTTP headers
5. If the authentication token is valid, then Sharepoint will send back a successful response

After doing the above steps, you should be able to access Sharepoint again.

The other way you can do it is you can contact the Customer Service to solve this error. You can try contacting them through their customer support number or their website. Then, the customer support will usually ask you to send them the error code that is appearing on your screen. They will tell you what to do next for your problem and give another solution.
